South Carolina DUI Laws And Local DUI And DWI Resources For South Carolina Residents

Introduction

South Carolina enforces strict DUI laws aimed at reducing impaired driving and protecting public safety. The consequences for driving under the influence are serious, even for a first offense. Offenders face criminal penalties, license suspensions, and mandatory substance abuse treatment programs.

Understanding South Carolina’s DUI laws is crucial for all drivers. The state applies a structured legal framework to DUI offenses, with clearly defined penalties and legal processes for arrest, sentencing, and post-conviction compliance.


DUI Law Overview

In South Carolina, DUI refers to Operating a Motor Vehicle While Under the Influence of alcohol, drugs, or other impairing substances. The law is enforced even if a driver is below the legal limit but shows signs of impairment that affect their ability to drive safely.

South Carolina BAC Limits:

  • Standard drivers: 0.08% or higher
  • Commercial drivers: 0.04% or higher
  • Underage drivers (under 21): 0.02% or higher

While the standard BAC threshold is 0.08%, drivers can still be charged with DUI if they are impaired by drugs or show diminished capacity behind the wheel. Underage and commercial drivers are subject to lower limits, and the presence of any detectable alcohol can trigger serious consequences for these groups.


Penalties by Offense

South Carolina uses a progressive penalty system for DUI offenses, increasing in severity with each subsequent conviction within a 10-year lookback period.

First Offense DUI

  • Fine: $400
  • Jail Time: 48 hours to 30 days
  • License Suspension: 6 months
  • Other: Mandatory enrollment in ADSAP (Alcohol and Drug Safety Action Program), possible ignition interlock device (IID) depending on BAC level

Second Offense DUI

  • Fine: $2,100 to $5,100
  • Jail Time: 5 days to 1 year
  • License Suspension: 1 year
  • Other: Mandatory IID, longer ADSAP requirements, community service may substitute jail time in some cases

Third Offense DUI

  • Fine: $3,800 to $6,300
  • Jail Time: 60 days to 3 years
  • License Suspension: 2 years (may be longer if prior offense was within five years)
  • Other: Extended IID requirement, stricter court supervision, increased treatment mandates

Aggravating Factors
Penalties may be increased if:

  • The BAC was 0.15% or higher
  • A minor passenger was in the vehicle
  • The DUI involved a crash, injury, or death
  • The offender refused chemical testing

A fourth or subsequent offense may result in a permanent driver’s license revocation and classification as a felony DUI with even more severe sentencing.


Citing the Statute

South Carolina’s DUI law is found in S.C. Code §56-5-2930, titled Operating a Motor Vehicle While Under the Influence. This statute defines the offense as driving while impaired by alcohol or drugs to the extent that the person’s faculties are materially and appreciably impaired.

Key provisions include:

  • Establishing legal BAC thresholds for different driver categories
  • Describing penalties based on offense number and aggravating circumstances
  • Providing guidance for administrative license suspensions
  • Outlining procedures for mandatory treatment through ADSAP

The statute is applied consistently across the state, and violations trigger both criminal prosecution and administrative penalties from the South Carolina Department of Motor Vehicles (SCDMV).


Local DUI Resources

South Carolina provides several resources to assist DUI offenders with education, treatment, and license reinstatement. These programs are often court-mandated and must be completed to regain driving privileges.

South Carolina Alcohol and Drug Safety Action Program (ADSAP)
ADSAP is a mandatory education and treatment program for all DUI offenders. Participants undergo assessment and are referred to the appropriate level of care. Completion is required before license reinstatement is considered.

LRADAC – The Behavioral Health Center of the Midlands
Serves Richland and Lexington counties with outpatient substance use treatment and DUI-specific education programs. Offenders often attend LRADAC after referral from court or ADSAP.

Charleston Center
Provides prevention, intervention, and treatment for DUI offenders in Charleston County. Services include group education, assessments, and follow-up counseling.

Keystone Substance Abuse Services
Offers DUI treatment, outpatient therapy, and recovery support in York County. Frequently used for ADSAP referrals and court-mandated programs.

The Phoenix Center

Legal Process in the State

A DUI arrest in South Carolina involves multiple legal steps, each with specific timelines and procedures. Both criminal and administrative consequences may occur in parallel.

Traffic Stop and Investigation
Officers may stop a vehicle for any traffic violation or if there is reasonable suspicion of impairment. Observable behaviors like swerving, delayed reactions, or odor of alcohol often prompt further investigation.

Field Sobriety and Chemical Testing
Police may administer Standardized Field Sobriety Tests (SFSTs), such as the walk-and-turn or one-leg stand. If probable cause exists, the driver is offered a breath, blood, or urine test to measure BAC.

Implied Consent Consequences
Refusal to take a chemical test under South Carolina’s Implied Consent Law results in:

  • 6-month license suspension (first refusal)
  • Mandatory ADSAP enrollment
  • Possible ignition interlock installation

These administrative penalties are separate from criminal charges and occur even if the driver is later found not guilty.

Arrest and Booking
Once probable cause is established, the individual is arrested, taken to jail, fingerprinted, and given a court date. Bail may be set depending on the severity of the offense and prior history.

Administrative License Action
The SCDMV handles license suspensions following a DUI charge or test refusal. Offenders may request a contested case hearing to challenge the suspension within 30 days.

Court Proceedings and Sentencing
The DUI charge is prosecuted in municipal or magistrate court. Sentences are based on prior offenses, BAC level, and any aggravating circumstances. First offenders may be eligible for minimum penalties, while repeat offenders face mandatory jail and long-term supervision.

Post-Conviction Requirements
DUI convictions typically require:

  • Completion of ADSAP
  • Installation of an ignition interlock device
  • Payment of all fines and fees
  • Compliance with probation terms or parole supervision

All requirements must be fulfilled before license reinstatement or reduction of penalties is possible.
